IMPROVEMENT IN MECHANISM FOR MAKING- WIRE HEDDLES.

To all whom it may concern Be it known that we, EMIL T. HEi TLE and RICH- ARD THoMPsox, both of the city, county, and State of New York, have invented a new and useful Improvement in Machinery for Making \Vire Hed'dles;

and exact description thereof, which will enable those skilled in the artto make and use the same, reference being bad to the accompanying drawingtbrming part of this specification, in which drawing- Figure 1 shows a longitudinal vertical section of one of the pincers of a machine for making wire heddles, with our improvement applied thereto, the pincers being shown open.

Figure 2 is a longitudinal section thereof',- taken when the pincers are closed.

Figure 3 shows a wire heddle made with our invention.

Figure 4 shows a wire heddle made without the aid of our invention.

Similar letters indicate corresponding parts.

This invention consists in holding or confining the strands of wire that compose the heddles, with rethe aid of is formed, in such a manner that the strands are not permitted to spring or bulge out while the strands are being twisted at the ends of the eye.

The letter A designates the pincers, or that part of a machine for making wire heddles between whose jaws those portions of the strands of wire which compose the central or warp-eye of a heddle are confined while the heddle is being made.

The lo'wer half, B, of the pincers, is hinged to the upper half 0, as shown at D, and the pincers are perforated at E to receive a pin, not shown, on which the pincers are mounted or supported in the machine.

The lower part or halt B of the pincers has across its jaw a die or former, 1 around which the heddleeye is formed, the strands being, in practice, arranged onopposite sides of thesaid die or former, the top of the die being then brought in contact with the upper jaw, so as to keep the strands from slipping over the die while the wire is being drawn further into the ma chine, and while the twisting mechanism in operation, closing the ends of the eye.

In making wire heddles by means of the improved machinery described in our Letters Patent of the United States granted to us July 11, 1868, for an improvement in machinery for making wire heddles, which Letters Patent were reissued tons November 9, 1869, by reissue No. 3,724, we find that as the distance between the twisting mechanism and the eye-forming die or pincers is lessened, and the parts are allowed to yield to the strain during the operation of twisting belly outward from the sides of thedie F, and the sides of the eye take a curved shape so as to increase the transverse diameter of the central or warp-eye of the heddle, as shown in fig. 4.

Our invention is intended to prevent the eye from taking or receiving such a shape, and to cause it to conform to the shape of the die or former, notwithstanding the yielding of the twisting mechanism toward the pincers.

\Ve accomplish this purpose by confining the strands of wire, and holding them along both sides of the die or former F during the operation of twisting the wire, as will now be explained.

The letter G designates a clamp whose upper part is pivoted at a, in a slot, H, in the upper part 0 of the pincers, in such a position as to be on the inner side of the die or former F, observing figs. 1 and 2, towards which side the point or end I of the clamp is directed.

\Vhen the pincers are being closed or opened, the

clamp G rests and slides on the lower jaw of the pincers, and, when the pincers are closed, its end I presses against the adjacent part of the heddle-eyc J, and holds it near the die or former.

The ends I of the clamps G K are, in this example, made narrow, but they can be made, if desired, wide enough to press against the whole length of the eye; but we have found, for eyes of ordinary length, that it is sufiicient for our purpose to press against the wire that composes the eye only at a single point, or along only a small portion of its length.

The opposite side or part of the strand which forms the heddle-eye is also confined or pressed inward in the same manner while the eye is being made, by the clamp K, which is pivoted near its lower outer corner, at I), in the slot L of the upper jaw of the pincers.

The upper edge of the clamp K projects through. the top jaw O of the pincers, where it works against the free end of a flat spring, M, whose other end is fastened to the top or back of the jaw, the object of the spring being to swing the clamp outward away from the die or former when the pincers are opened, and its outward inovementis limited by means of pins, N, that project from its sides near its front, and strike the bottom of a curved slot, 0, made across the upper side of the pincer-jaw 0.

hen the pincers close, the point of the clamp K comes in contact with the face of the lower jaw B, and said clamp K is thereby turned inward on its pivot, against the force of the spring M, its pins N N moving up away from the bottom of the slot 0, which is curved eccentric-ally about the pivot b.

\Vhen the strands that are to compose the heddle are drawn in between the jaws of the pincers, the

jaws are closed, the die or former coming between the strands, and the clamps Gand K, as the pincers close, come against the strands and guide and hold them in proper position with respect to the die or former while the heddle is being made and the ends of the eye are being formed by the twisting of the strands about each other, and the eye is thereby made with its sides straight and symmetrical, corresponding to the shape of the die or former, as is illustrated in the case of the central or warp-eye shown in fig.

The clamp G is controlled as to the height to which it can rise in its slot by the stop-pin I placed across the upper part of slot H forward of the pivot a, so that the clamp is prevented from rising off the lower jaw when the pincers are closed, and, in the case of the clamp K, the same result is accomplised by pivoting the clamp in such a manner that its bottom edge comes below the face of the upper jaw a distance about equal to the height of the die F, and placing the pivot b behind the center of the clamp.

What we claim as new, and desire to secure by Letters Patent, is I 1. The mechanism for holding and confining the sides of the heddle-eye along the sides of the die or former F during the operation of the twisting mechanism, substantially as and for the purpose described. 2. The clamps G K combined with the pincers A, substantially as described, so that they are moved automatically towards the die or former by the operation UlUSlng the pincers, substantially as described.

This specification signed by us this 26th day of J anuary, 1870.
